Preschool Development Grants Birth-5 (PDG B-5) will fund states to develop, update, or implement a strategic plan to facilitate collaboration and coordination among early childhood care and education (ECE) programs in a mixed delivery system to prepare low-income and disadvantaged children to transition into the local educational agency or elementary school. With a focus on efficiency and coordination, shared services is one helpful approach to achieve this goal. A Shared Services Alliance allows individual programs to stay small where being small matters and be big (achieve scale) where being big matters. (author abstract)
